Running a Private Blog Network or buying links from a PBN

Hi everyone. I'm checking with you guys if you have any experience with this. So what I'm doing is deeper research on PBNs, and I would really love to get a picture of what it takes to successfully run a PBN and stay under the radar.

Are you running a PBN, and how difficult is it? What do you think about the risks?

Have you bought links from a PBN and how did it go? What is your backup plan if G deindexes the PBN?

So I just released a video about why I believe this is a very risky strategy. In this video, I talk about my experience investing over $1000 on Fiverr testing random traffic gigs with 1-3 Tier Networks and other traffic gigs. It was a long time ago, but it ended up being a complete failure when it came to ranking on Google or making money online.

I also talked about something I thought was suspicious when I checkeda thread at aforum market place (not this forum). I need to know if this is common practice or if I just imagine it.

Then I talk about people that have been unsuccessful for a long time, and I shed light on the reason why that is. I talk about how I changed my strategy to something that makes sense. It is just disappointing that I didn't do this 10 years ago.

I'm not sure if I'm allowed to link to my video, so I'll refrain from doing that,but it would help explain what I mean. Let me know if I can add it. Thank you.
